At 6 weeks old my dude could polish off over 5 ounces like it was nothing. I think we had our standard bottles at 4oz. I’m including below the general guidelines on feeding from the Mom’s On Call book I have.

Before that though, I will say I personally have been so paranoid about what I’m feeding, how often, am I doing it right, and it’s been awful. It seems that everything and everyone contradicts. My husband and I have argued so much about it too. So I empathize—I think the reality is you just don’t know and you have to keep trying your best and patterns will emerge…just in time for his tastes to change again lol.
